Fire Stopping / Penetration Seals:

Fire stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fireproofing of a wall or floor assembly allowing it to impede the spread of fire and smoke.

All fire stopping works are fully tested and clearly identifiable by our logging system of stickers, photos and log sheets using real-time technology which we make available to our clients. This information provides a ‘Golden Thread’ of works undertaken in line with the specified fire strategy and Part B building regulations.

M Construct work in accordance with third party accreditation and material manufacturers to ensure our fire stopping technicians are fully trained and up to date with any new regulations and fire-stopping methods

Fire Rated Partitions and Ceilings

M Construct provides a high quality and professional installation of all fire rated dry lining systems, which are becoming more and more common requirement in today’s buildings. We can deliver varied services whether it is a simple additional office refurbishment or a major new construction development. Our operatives are highly experienced with the latest manufacturer’s innovative designs. Our teams are always ready to offer support from the initial design stage to completion.

Fire Rated Partitions and Ceilings are designed and installed to form separate compartments within the fabric of a building.

  • Fire Rated Partitions

Depending upon location and functionality within your building, partition walls may be expected to fulfil different requirements in the event of a fire and these should be taken into account at the planning stage.

Generally, fire resistant walls used for partitioning buildings and enclosing compartments will be required to provide a barrier to the passage of fire from one side to the other. Building Regulation requirements for use such as offices and factories, generally require a minimum 30 minute fire resistance rating to any partitioning within the area.

The walls must be able to satisfy each of the relevant criteria, such as integrity, insulation and in some cases, load bearing capacity.

  • Fire Rated Ceilings

When it comes to ceilings, there are effectively two properties that may be required involving fire. The first is reaction to fire: This measures how a suspended ceiling will react when in contact with fire. There are Building Regulations in force regarding this and the table below shows the current requirements.

Euroclasses rate from A1 to F, with A1 being the best reaction to fire performance and F being the worst.

Building Regulations area (non-residential) Euroclass
Circulation Areas A1
A2-s3, d2
B-s3, d2
Other Rooms (over 30m2) C-s3, d2
Small rooms (up to and including 30m2) D-s3, d2
Product Cannot be used E-d2, F

The second relates to structural fire protection.

This is only required in certain areas, for example in corridors that are used as fire escapes. A fire-rated ceiling will have been tested by the manufacturer to retain structural integrity for a set period of time (usually 30 or 60 minutes), and indicates how effectively the ceiling can hold back fire and prevent it from spreading from room to room.

There are many national testing methods used to establish the structural fire protection performance of a suspended ceiling system and several European norms that are acceptable in most European countries.

With our knowledge of available systems for most scenarios and requirements, we would provide a comprehensive survey and design service with full client involvement throughout, to offer the most cost-effective solution to the individual’s needs.

Fire Curtains

Fire curtains prevent the spread of fire and smoke through voids and also provide compartmentation between different areas within buildings.

M Construct can install and maintain both lightweight flexible fire curtains or insulating fire barrier curtains to provide up to 120 minutes fire protection within both occupied and unoccupied facilities.  This includes lofts, ceiling voids and risers and the fire curtains ensure no fire or smoke can spread from one compartment to the next.

With roof voids we carry out surveys to highlight what is required to make sure buildings are in accordance with building regulations and to ensure that fire compartment walls are continued above the ceiling and into the roof void.  If required we can also provide and install fire-rated access hatches, walkways and handrails for the roof space as well as improving its insulation.

All fire curtains installed by M Construct are fully tested, certified and comply with the relevant BS or EN standards.

Cavity barriers

Cavity barriers are a cost-effective way to buy you time in the event of a fire. Time that could save lives and protect your property investment. Cavity barriers are pieces of fire-resistant material that are used to seal cavities. This is to prevent the spread of fires through the cavity wall.
We recommend cavity barriers in the ceiling and roof voids, in the external envelope of your building, and horizontally in high-rise buildings in the void between the edge of the concrete slab and the external envelope of the building. Underfloor cavity barriers can also seal the voids between raised access floors and floor slabs.

Here’s what those applications look like:

1.Ceiling and roof voids
A light, flexible, passive fire-protection option that looks like fabric. We install into the roof void created by suspended and modular ceilings.
Fire-resistant up to one hour.

2.Rainscreen cavity barriers
We use rainscreen cavity barriers in the external envelope or fabric of buildings to ensure the system drains freely and maintains airflow. They provide an effective hot smoke and fire seal.
These barriers are made from non-combustible stone wool, within a polythene sleeve. We fit them vertically or horizontally to provide a robust fire, acoustic and thermal barrier within external wall cavities and party walls.

Exceeds minimum Building Regulation requirements in concealed wall cavities
Resilience – not affected by building movement, shrinkage or thermal change
Robust – last as long as the building does
Can be used vertically or horizontally
Excellent acoustics – prevent flanking noise transmission
Up to 60 minutes of integrity.

3.Slab edge barrier
We install slab edge barriers in high-rise buildings horizontally in the void between the edge of the concrete slab and the external envelope of the building.
Slab edge barriers are rock-fibre compressible slabs with an ablative coating that offer a fire and smoke seal of up to four hours.

A low-cost barrier
Fast installation – minimal disruption
Fully tested
Up to four hours’ integrity

4.Underfloor barriers
It’s vital to seal the voids between raised access floors and floor slabs to prevent the spread of fire and smoke. We fit barriers designed to provide cost-effective cavity fire stops in these voids. This is a one-piece system that’s fast to cut and install, so you’ll have minimal disruption. These systems offer a tight vertical fit and offer up to 120 minutes of fire resistance. Time enough to get people out and professionals in.

Fast installation
Great acoustic performance
Provides a smoke and fire seal for up to 120 minutes
BS EN ISO 9001-approved for peace of mind
Fits voids up to 1000 mm.

Boards / Structural Steelwork Protection

Current regulations require certain elements of the building structure to have fire resistance. Fire resistance testing on structural steel members have shown, that by incorporating a proprietary fire protection system, the ability of the structure to resist fire will be greatly enhanced dependent upon the particular system chosen.

Boarded fire protection systems offer a non-combustible and cost efficient method of providing up to 240 minutes fire protection to structural steelwork. As the original means of affording structural fire protection, this method has seen major developments in the types of boards available today.Boarded fire protection systems can be durable, resistant to water and beneficial to acoustic performance. Certain fire boarded systems are able to accept decorative applications, such as paint or plaster, providing an aesthetic finish without the need for further preparation

Materials we use:

  • Glasroc F board encasement
  • Beam Clad
  • Fire line board
